THE CONWAY POLXNOMIAL INVARIANTS FOR A CLASS OF KNOTS
一类纽结的Conway多项式不变量

In this paper,a special class of knots has been studied.It is proved that there exist infinitely maily knots with only two negative crossings,whose Conwny polynomials are not positive.In fact, a general formula of Conway polynomials for the class of knots is given.
